315/5 = x/9....315 miles to 5 hrs = x miles to 9 hrs
cross multiply
(5)(x) = (315)(9)
5x = 2835
x = 2835/5
x = 567
He will drive 567 miles in 9 hrs
First, we subtract 20% of the amount from x, so the initial cost of the furniture should be 80% of x or 0.80x. Then, due to the sales taxs, this amount should be added with 6.25% of itself. Such that,
A = 0.80x + 0.0625(0.80x)
= 0.85x
Hey there! :D
So you're wondering if you can make a new ten in this problem, right? Well, lets find out! We can simply do<span> 59 + 17 = 59 + 1 + 16 = 60 + 16 = 76. When we did 59 + 1, that is a new ten then we added to 16. So yes, we did make a new ten in this problem. </span>
<span>Hope it helps! ;)</span>
<span>So you would subtract 12 from both sides to get 60 equals 4x. Divide both sides by 4, and you get x=15. So she has sold 15 shirts. </span>
